Can High Blood Sugar Make You Dizzy?
Yes, high blood sugar can cause dizziness through several mechanisms. When blood glucose levels exceed 180-250 mg/dL, your body attempts to eliminate excess sugar through increased urination, leading to dehydration and electrolyte imbalances that trigger dizziness. High blood sugar also affects blood circulation and can cause blood vessel changes that reduce oxygen delivery to the brain. Additionally, diabetic ketoacidosis—a serious complication when blood sugar exceeds 250 mg/dL—frequently causes dizziness alongside nausea and confusion. If you experience persistent dizziness with blood sugar readings above 180 mg/dL, check for other symptoms like excessive thirst, frequent urination, or blurred vision and seek medical attention promptly.
